This invention relates to umbrellas and more especially to theconstruction of the frame of an umbrella.

Heretofore it has 'tice to connect the ribs and stretchers to each otherand to and wires. The wires have been used on the sleeve and top notchand when one of them 7 has become broken all of the parts engagedthereby have been released. This and other have been present whereumdisadvantages brellas have utilizedthese old forms of con nectingmeans.

It is an object of-the present invention to improve upon the connectionsbetween the movable parts of an umbrella by providing ball and socketjoints which can be easily made, readily assembled, and will hold theparts together securely.

Another object is which are compact and donot add objectionably to thebulk of the umbrella when closed.

WVith the foregoing and other objects in view which will appear as thedescription proceeds the invention resides in the combination andarrangementof parts and in the details of construction hereinafterdescribed and claimed it being understood that changes in the preciseembodiment of the invention herein disclosed may be made Within thescope of what is claimed without departing from'the spirit oftheinvention.

In the accompanying drawings the preferred form of the invention hasbeen shown.

This enlarged portion is seated in the laterally bulgedintermediate portion 17 of a sleeve 18 which, as shown in Figures 8 and12, is seated in the channel in the rib and has side flanges 19 whichlap the outer surface of the rib. That portion of the sleeve E.

in the channel is shaped at its center to form a socket member 20 havinga slot 21.

In assembling this sleeve with the rib: the ball 9 at the outer end ofthe stretcher 12 is laced between opposed portions of the soc et 20after first spreading them apart at the slot 21. Said opposed portionsare then drawn together to the normal positions shown in Figure 11 andthe flanges 19 are bent back of the rib as shown in Figure 8. Thus theball on the stretcher will be held securely to the rib and as it is alsoseated in the enlargement 16, the sleeve will not become displacedlongitudinally of the rib. The slot 21 Will allow the stretcher to swingtherein relative to the sleeve.

The several parts o't the frame can be readily assembled, as will beobvious, and by reason of the construction of the connections. saidparts Will be held together secure- 1y, will work freely, and willpermit the parts to lie compactly when the umbrella is closed.

What is claimed is: 1. In an umbrella the combination with a ribchanneled longitudinally, said channel being enlarged at a point betweenits ends to constitute a concave bearing, of a sleeve fitted in thechannel and having an integral socket portion intersected by a slot, theside portions of the sleeve embracing the rib, a stretcher mounted toswing Within the slot, and a ball on the stretcher movably mountedwithin and retained by the socket portion and the concave surface of therib.

2. In anumbrella the combination with a ribchanneled longitudinally, ofa sleeve em bracing the rib having an integral socket portion closed bythe rib, there being a slot intersecting that portion of the socketremote from the rib, and a stretcher extending through the slot andanchored at one end in the socket. 4

3'. In an umbrella the combination with a rib channeled longitudinally,of a sleeve embracing the rib, having an integral socket portion closedby the rib, there being a slot intersectingthat portion of the socketremote from the rib, a stretcher extending through the slot, and a ballon the stretcher anchored in the socket, said socket being disposedwithin the channel in the rib.

In testimony that I claim the foregoing as my own, I' have heretoaifixed my signature.
